I remember that thread, Bubble
Ray, it was easy
With the two brackets already installed, I had the empty housing mounted to the control arms, and raised and supported it in the chassis, at ride height.
I then simply unbolted the left upper from the housing, and lifted it to the point where I wanted the new bolt location to be ( about 1 3/4" ), and propped it up there. I then made a pair of carboard templates, and cut some 3/16" plate in the shape I needed them, and tack wended them to the tops of the existing bracket on the housing... marked where the hole has to be, pulled them back off, went to the drill press, and drilled the two new holes.
Went back to the car, placed the two plates on top of the existing left-side control arm bracket, ran the bolt through the assembly ( plate / control arm bushing / plate ), and welded the plates to the top of the bracket.
Not close... just a very simple way to get it dead on.
Then I reversed the procedure for the right side.
The factory shims are still in the upper mount at the frame, I'm using factory upper and lower arms... so the housing is where the factory put it. Nothing disturbed.
What did it do ?
Well, for the first time in this car, when I launched it on clean, new pavement... I got that jump/lunge that I've been seeking for three(3) years
Mind you, I still had to use no more than about 2/3 throttle, letting the clutch out at about 4000 RPM...
When the front tires came off the ground in the first 20 feet, I got excited, floored it... und spun the slicks off again.
Rear shocks too loose... wouldn't let the rear come back down when the nose was up... hampering the weight transfer.
Just a shock tuning problem now... which by comparision, is easy !
